High Efficiency Heat Pipe Evacuated Tube Solar Collector

The Heat Pipe Solar Collector is designed to convert solar energy into usable thermal energy for domestic hot water, building heating and other solar thermal applications. Based on evacuated tube technology and sealed heat pipes, it provides an efficient and reliable method of transferring solar heat without water flowing directly through the heat pipes.

Its enclosed heat-transfer structure, corrosion-resistant materials and flexible configuration make it suitable for residential installations as well as commercial and large-scale solar thermal projects.

Sealed Heat Pipe Technology

The core of the collector is a sealed heat pipe containing a working fluid. When solar radiation heats the lower section of the heat pipe, the working fluid vaporizes and moves rapidly toward the condenser section.

At the condenser, the heat is released to the circulating water or heat-transfer medium. The working fluid then condenses and returns to the lower section, completing the heat-transfer cycle.

This phase-change process enables rapid movement of thermal energy through the heat pipe while keeping the heat-transfer circuit enclosed.

Water-Free Heat Transfer

Unlike collectors in which water flows directly through the heat collection tubes, the heat pipes are fully sealed and water-free.

This structure helps reduce the risk of freezing, bursting and leakage within the heat pipes and minimizes the influence of water quality on the heat-transfer components.

It also supports reliable operation across changing seasonal conditions, making the collector suitable for both colder climates and areas with hot summers.

Rapid Thermal Response

High-conductivity metal heat pipes transfer absorbed solar heat efficiently from the collector tubes to the condenser section.

The combination of evacuated tubes, aluminum fins and high-purity copper channels provides an effective thermal path for solar energy. 3003 aluminum fins help collect and transfer heat, while copper components provide high thermal conductivity and corrosion resistance.

Durable Collector Construction

The collector is assembled with materials selected for long-term solar thermal applications.

Silver-copper welded connections provide strong and durable joints, while the enclosed heat-pipe structure helps protect the thermal circuit from external water exposure.

A suitable heat-transfer medium can be selected according to the local climate and system operating conditions.

Flexible System Configuration

Solar thermal projects vary in building size, installation conditions and thermal demand. The collector can therefore be customized in terms of size, structure and configuration to suit different project requirements.

It can be incorporated into systems for:

1. Residential hot water

2. Commercial hot water

3. Building heating

4. Swimming pool heating

5. Centralized solar thermal systems
